lambda error

[cordobabrendy]

cars now had 4 lambda sensors in total in a year odds, the first two fixed the problem but since going through a puddle im getting the lambda malfunction error code and engline light on, last time i ran vagcom the sensor both pre and post seemed to be giving signals (whether they are correct or not...pass) dealers are now going on about how i must be remapped and that my car needs putting totally 100% back to standard otherwise they wont do anything.... they did suggest maybe taking the car to their other dealership where the master tech resides.
i really need to get to the bottom of this as its making the car stutter intermittantly in the lower gears.
any ideas? coil packs were also replaced in case they were causing the misfire that could be killing the probes.

new maf etc, was replaced a few months ago.
vagcom is saying lambda sensor error. clear the fault and its straight back .

ok well i only had a maf about a year ago i thought it cant need replacing already my car has the symptons yours has but only when its been warmed up after about 5 mins of driving does it start to sort of misfire

the misfire calmed down after a week or so, so for the last 2 months now its just a bit stuttery in lower gears, it might still happen in higher gears but not noticeably.

Brendy - I thought you had Revo Stage 2...... which ignores second Lambda.

i think its the front lambda mate, even if it was the second one, why would it now be lighting up on the dash?

Sorry mate, I misunderstood you. You seemed like you were talking about faulty pairs of lambdas..
